Calibrachoa plant named ‘Cal Cremey’

ABSTRACT

A new  Calibrachoa  plant particularly distinguished by medium, cream-white flowers with red markings and yellow throats, early and continuous flowering, medium green foliage with lanceolate leaves, a medium size, medium vigor, bushy, and a spreading to semi-trailing plant habit with good branching ability, is disclosed.

Genus and species: Calibrachoa sp.

Variety denomination: ‘Cal Cremey’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Calibrachoa, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name ‘Cal Cremey’. The new cultivar originated from a hybridization made in October 2001 in Gilroy, Calif. The female parent was the proprietary pale-rose flowered Calibrachoa plant ‘389-1’ (unpatented), while the male parent was the proprietary Calibrachoa plant ‘355-1’ (unpatented) having pale-orange flowers with an eye. The seeds produced by the hybridization were sown in April 2002 in Gilroy, Calif. A single plant selection was chosen for further evaluation and for asexual propagation in Summer 2002 in Gilroy, Calif.

The new cultivar was created in 2002 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. over a two-year period. ‘Cal Cremey’ has not been observed under all possible environmental conditions. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in Canada on Jul. 19, 2005, in Switzerland on Sep. 16, 2005 and with the European Union on Sep. 28, 2005.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Gilroy, Calif. and Hillscheid, Germany.

-   -   1. Medium, cream-white flowers with red markings and yellow         throats;     -   2. Medium-green foliage with lanceolate leaves;     -   3. Medium size, bushy, plant habit;     -   4. A spreading to semi-trailing plant habit;     -   5. Good branching ability with medium vigor; and     -   6. An early and continuous flowering response.

DESCRIPTION OF PHOTOGRAPHS

This new Calibrachoa plant is illustrated by the accompanying photographs which show overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants grown in a greenhouse in Hillscheid, Germany.

FIG. 1 shows the overall plant habit, including blooms, buds and foliage of a 25-week old plant in late Summer of 2005.

FIG. 2 shows a close-up of the mature inflorescences of an 11-week old plant in May 2005.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Cal Cremey’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 6-week old unpinched plants which were planted as rooted cuttings in 12-cm pots in July 2005, and then grown in a greenhouse. Observations were made when the plants were in full flower in August 2005. Color readings were taken under natural light in the greenhouse. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Cal Cremey’ differs from the female parent ‘389-1’ (unpatented), by having large, cream-white flowers, while ‘389-1’ has smaller, pale-rose flowers. In addition, ‘Cal Cremey’ has a more upright, less decumbent plant habit than ‘389-1’.

‘Cal Cremey’ differs from the male parent ‘355-1’ (unpatented), by having cream-white flowers, while ‘355-1’ has pale-orange flowers. In addition, ‘Cal Cremey’ has smaller leaves and more basal branching than ‘355-1’.

‘Cal Cremey’ differs from the commercial cultivar ‘Cal Ivory’ (U.S. Plant Pat. No. 14,544), by having cream-white flowers with a more distinct yellow throat and a red ring, while ‘Cal Ivory’ has light yellow flowers with a less distinct yellow throat and no red ring. In addition, ‘Cal Cremey’ has shorter branches (about 70% of the length) than ‘Cal Ivory’.
